ABSTRACT:
In an automatic coffee brewing machine of the type having container means for receiving cold water at the start of a brewing operation and dispensing hot water at the end of the brewing operation, a control means comprising heating means activated to its closed position when sensing a temperature below a predetermined first value resulting when said container means receives cold water at the start of a brewing operation and being activated to its open position when it senses a temperature above a predetermined second value higher than said first value, electrical connecting means joining said switch means with said heating means, and a heating element for heating said switch means when the switch means is in its open position, so that when said switch is in its closed position at the start of a brewing operation the heating means is fully energized to heat the container means and the water contained therein until said switch means is activated to its open position when the temperature of the container exceeds said second value after which the energization of said heating element maintains the temperature sensed by said switch means at a level between said first and second values which prevents said switch means from being activated to its closed position and reheating the container before the start of a new brewing operation.
